FAQ

You must specify in Seller Portal that your binary is compatible with all new devices (a watch with an upgraded OS is considered a new device) and republish your app. After your updated app is published, it will be available to those new devices.

On Gear S3 and Gear Sport watches, the Tizen OS can be upgraded. Gear S3 can be upgraded from Tizen 2.3 to Tizen 3.1 or 4.0.0.1. Gear Sport can be upgraded from Tizen 3.0 to Tizen 4.0.0.1.

If you published your app before these upgrades were available, the option to include the upgraded watch as a compatible device was not available in Seller Portal. For example, if you published your app before Tizen 4.0.0.1 was released, your selections for compatible Gear Sport watches in Seller Portal would have been for Tizen 3.0 only. Likewise, your selections for compatible Gear S3 devices would have been for Tizen 2.3 and 3.0. As a result, a customer who has upgraded their watch to Tizen 4.0.0.1 will not be able to view your app in the Galaxy Store.

In order to have your watch app recognized as compatible with an upgraded watch, you must update the compatible devices for the binary in Seller Portal. In general, if a new device is released or an existing device becomes upgradable to a new OS after you have published your app and you want your app available on these devices, you must update your binary to be compatible with these devices and republish your app.

To update the list of compatible devices for your binary file in Seller Portal:

Log in to Seller Portal and open your watch face app.

Click the Binary tab.

At the top of the Binary section, in the middle is a box with Selected Device(s) and the total number of selected compatible devices. Click on the number.

In the Detailed Device Settings window, select each device with which the binary is compatible. If your binary is compatible with all listed devices, click Select All.

Click Save.

Submit your app for validation and, after it has been successfully validated, republish it.

Make your Galaxy Watch face or app stand out in the Galaxy Store.

Samsung recommends that you use portrait-orientation product images for your Galaxy Watch detail page. Users can just tap on a portrait image to open it in full-screen mode, creating an optimal phone experience and allowing your app to stand out in the Galaxy Store.

Best practices

Use detailed, close-up images of the product. We suggest that you use just the product and logo (with minimal or no text) for a strong image that shows the quality of your workmanship.

Avoid using identical images for the icon, cover image, and screenshot. In this case, the detail page shows three duplicate images rather than three separate views of the product.

Screenshot resolution

We suggest the following resolution guidelines for screenshots:

Cover Image = 1024 x 500 pixels

Horizontal Screenshots = 1500 x 750 pixels

Vertical Screenshots = 550 x 1100 pixels

Galaxy Store Asset Creator

The distributor certificate is used for signing and verifying your app. It identifies the distributor (for example, Galaxy Store) and grants privileges to that distributor. For testing purposes, it ensures that your signed application is installed on registered devices only.

In order to test your app on a device, the device must be registered in your personal distributor certificate. Then, you must build your app, which signs the app using your personal distributor certificate.

To generate a personal distributor certificate and register a Samsung device,

Using the Galaxy Watch Studio (formerly Galaxy Watch Designer), from the main menu bar, click Project > Distribute Certificate. For more information, see Get Your Certificates.

Using Tizen Studio, from the main menu bar, click Tizen Tools > Certificate Manager (the Samsung Certificate Extension must be installed in order to properly generate a personal distributor certificate for your Samsung device). For information about the Samsung Certificate Extension, see Installing Certificate Extension. For information about the Certificate Manager, see Creating Certificates and Managing Certificate Profile.

The personal distributor certificate is used for testing only. When you release your app for sale in the Galaxy Store, your personal distributor certificate is replaced by an official distributor certificate.

If you upgrade a registered device (for example, you upgrade the Tizen OS), you may need to re-register the device in your personal distributor certificate. For example, if you upgrade your Galaxy Watch 3 or Sport watch to Tizen 4.0, you must re- register the device in your personal distributor certificate and rebuild your app before testing it on the device.

You may encounter one of the following error messages if there is a problem with the distributor certificate:
